3 210 series spring loaded models PITIES to FH EMERGENY EXPOSURE psi INLET PRESSURES to 10 psi OUTLET PRESSURE w.c. to 42 w.c. The 210 series is a lock-up type regulator and complies with codes using the specification. The 210 series has been designed for maximum control functions in an easy-to-use package. For gasfired boilers, steam generators, industrial furnances, ovens and similar high demand equipment. alanced valve design eliminates the inlet pressure effect acting on the valve. Regulating stability is improved and hunting tendencies reduced by the use of dampening mechanisms in both the breather outlet and sensing tube. You get precise regulation over a broad range of pressures and flow rates with a Maxitrol 210, including zero governor application. Housings of the 210D, E & G models are of high-strength aluminum alloy. The housings are reinforced with webs for maximum strength. The 210J models are of cast iron and steel construction with 125 pound flange connections..... Internal parts are cast or machined from corrosion resistant metals or are electro plated. Diaphragms are of the finest quality synthetic coated fabrics. The regulators are painted providing a protective coating if used out-of-doors. for pipe size, make sure regulator is not more than one size smaller or one size larger than manifold pipe size. For zero governor applications, a counterspring is mounted beneath the valve. maximum inlet pressure of 5 psi is recommended. Outlet pressure may be adjusted from -1.0 w.c. to +1.5 w.c. The Maxitrol 210 is designed to operate as a zero governor in the normal upright position. SENSING TPS VILLE Tap locations are available for downstream sensing, cross connections, and differential control. Four convenient locations can be tapped and plugged for measuring pressure. Vertical vent tapped - 3/8 NPT on 210D, 3/4 NPT on 210E, G & J 210 series industrial regulators are intended for use with all fuel gases. mbient temperature limits are F to F. Maximum emergency exposure pressure is 25 psi. t this pressure, the regulator will suffer no internal damage but it may not provide accurate regulation. The regulator should be mounted in an upright position in a horizontal pipe run. Gas flow must be oriented to arrow on bottom casting. When selecting. Internal sensing #7 furnished as standard..

7 220 series pilot loaded models NOT.G.. ERTIFIED PITIES to FH EMERGENY EXPOSURE psi INLET PRESSURES to 10 psi OUTLET PRESSURE psi to 5 psi The 220 series, utilizing a servo-operated design rather than the more conventional spring-loaded design, delivers higher outlet pressure than the spring loaded models. The main diaphragm on the Maxitrol 220 is loaded with gas pressure rather than with a spring. This gas pressure is precisely controlled by a small pilot regulator in the upper housing. When the regulated outlet pressure of the pilot regulator is changed, by spring adjustment, the outlet pressure of the main regulator will change proportionately. Outlet pressure adjustments are readily made by first removing the hood of the Maxitrol 220. Then remove the cap atop the pilot regulator, which exposes the adjusting screw, and adjust to desired pressure. Three positions can be tapped and plugged for making inlet or outlet pressure readings. The fourth position is used to supply inlet pressure to the pilot regulator. Remote sensing is also available. 220 series industrial regulators are intended for use with all fuel gases. The regulator will perform most accurately when mounted in an upright postion in a horizontal pipe run. Gas flow must be oriented to arrow on regulator. When selecting for pipe size, make sure regulator is not more than one size larger or smaller than manifold pipe size. Single vent, equipped with model 1206 vent limiting orifice, is located in upper housing. mbient temperature limits are F to F. Maximum emergency exposure pressure is 25 psi. t this pressure the regulator will suffer no internal damage but it may not provide accurate regulation. Two outlet pressure adjustment springs are available. R (K spring) psi to 3 psi R (L spring) psi to 5 psi
